Specification of Letters Patent.

7 Application filed February 16, 1906. Serial No. 801,397.

To all whom, it may concern.-

Be it known that 1, ROBERT S'rooK, a citi- Zen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Barrel Valves and'Tapping Devices, of which the following is a specification.

This invention relates. to a valve and tapping device which is intended more particularly for use on beer-barrels for connecting the same with the conduit through which the beer is drawn off from the barrel.

The object of this invention is the production of a valve and tapping device of this character which is simple and durable in construction, which will securely close the liq uid-passage, which can be readily repaired without takingthe body of the valve out of the barrel, and which will permit of draining the entire contents from the barrel.

, In the accompanying drawings, Figure 1 is a longitudinal section of my improved valve and tapping device, showing the valve in an open position and connected with the co11P- ling attached to the delivery-conduit. Fig. 2 is a cross-section in line 2 2, Fig. 1. Fig. 8 is a view similar to Fig.- 1, showing the valve in a closed position and the coupling shifted accordingly. Fig. 4 is a cross-section in line 4 4, Fig. 3.. Fig- 5 is a longitudinal section of the valve-body, showing the means for tightening the valve-disk and also for locking the sameyieldingly in its closed position. Fig. 6 is a side elevation of the coupling whereby the valve is coupled with a dischargeconduit.

Similar letters of reference indicate corresponding parts throughout theseveral views. A represents the hollow body or casing of the valve, which is preferably constructed in the form of a cylindrical bushing, havingJan external screw-thread (1, whereby the same is secured in an opening formed in the barrel B. (Shown by dotted lines in Figs. 1, 2, and 3.) At its outer end the valve-body is provided with an external annular flange c, which bears against the outer sideof the barrel. The inner end of'the valve-body when secured to the barrel is practically flush with the. inner side thereof, enabling the entire contents of the barrel to be drawn ofl, which is impossible in the valves of this character heretofore used, inasmuch'as the latter projected a considerable distance beyond the inner side of the barrel. At its inner end the valvebody is closed by a head D, having two outlet ports or openings dd on opposite sides of its center.

Fatented Jan. 15, 1907.

E represents the valve-disk, arranged axially withinthe inner part of the body and having secured to its inner side or'face a packing-disk or Washer F, of rubber or similar material, which engages with the outer side of the valve-head This valve-disk and packingare pivoted centrally to the inner side of the valve-head by means of a screw g, bearing with its head against the outer side of the valve-disk. On opposite sides of said pivotscrew the va1ve-disk and packing are provided with coinciding ports 6 f, which may be moved into and out of register with the ports (1 in the valvehead D for opening or closing the passageway of the valve.

H represents laterally-projecting locking or tightening lugs arranged on diametrically opposite sides of the valve-disk and adapted to engage with the inner sides of segmental locking-ribs 7L, arranged oircumferentially at the inner end of the bore of the valve-body on opposite sides thereof. The ends of the lock ing-ribs are separated by intervening spaces or gaps h, which are slightly wider than the locking -lugs H. The valve disk may be passed into the inner or front part of the body by placing its locking-lugs in line with the gaps between the ends of the lockingribs, and the valve-disk may also be removed from the body in like manner. .By pivotally securing the valve-disk and its packing to the head of the valve-body by a screw from the outer end or side of the valve-body it is possible to renew or repair this valve without r e moving the body from the barrel, thereby avoiding wearing out the opening in the barrel which receives it and rendering it unnecessary to replace .that part ofthe barrel containing the valve-opening, as is commonly the case when valves are employed which must be entirely removed from the barrel to permit of repairing the same.

After the valve-disk and its packing have been seated against. the outer side of the head D and pivotally secured thereto by the screw 9 the passage-way through the valve may be opened or closed by rotating the valve-disk and packing so that the portsthereof are moved into or out of register with the ports.

' latter will be crowded inwardly and caused to press the packing firmly against the outer side of the valve-head and produce a liquidtight joint between theseparts. Stops j are preferably arranged at the highest part of the inclined faces of the locking-ribs h in position to be engaged by the lugs H of the valve-disk when the parts wear unduly and limit the movement of the valve-disk in this direction, was to prevent disarran'gement of the parts. While the valve-disk closes the outlet or passageway of the valve in this manner, the barrel is in condition to be shippedor transported in the usual manner.

In order to prevent the valve-disk from being opened accidentally by the jarringaction to which the barrel is subjected during transportation, one or more detent or locking springs K are provided. Each of these springs is secured at oneend to'thevalvehead opposite one of the locking-ribs and is provided. at its free end with a should er, nose, or offset portion 1c, which isadapted to engage against the rear side of one of the locking-lugs when the valve-disk isin its closed position, as represented in =Fi g. 5. These springs eXert sufiicient pressure against these lugs "to prevent accidental opening of the valve-disk, but yield readily when the valvedisk is turned manually by means of a suitable tool when it is desired to open the valve. By interlocking the Valve at itsperiphery with the body when in its closed position the same is securely held against leakage in its closed position and without straining the screw g, which pivotally secures the central part thereof to the valve-head.

L represents the coupling whereby the valve is connected with the discharge-conduit m (shown by dotted lines in Figs. 1 and 2) and whereby the valve-disk is turned for connecting the interior of the barrel with said conduit. This coupling comprises a tubular nozzle Z, connected with the discharge-conduit m, a cylindrical stem Z, arranged at the inner end of the nozzle, a pair of locking lugs n 12,, arranged on opposite sides of the stem,

and an annular flange o,arrang'ed at the junction of the stem and nozzle. Atthe inner end of the coupling-stem the same is -pro vided with acentral recess p, which is adapted to receive the head; atthe outer end of the pivot-screw g. On opposite sides, ofthis recess the stem is provided with two coupling sockets or recesses g g, which are adapted to receive two coupling pins, lugs, or projections g g, arranged on the outer side of the valve,

disk on opposite sides of its center.'

r 1' repres'entatwo passages or ways arranged lengthwise in the stem of the coupling J on opposite sides of its center'and alternating with the sockets q. These passages are connected' at their outer ends with the interior of the dischargenoz'zle, while their front ends are adapted to register with the ports of the valvedisk' when the coupling-stem is -inserted in the rear or outer part ofthe valvebody and its sockets q areengaged'withthe coupling-pins 0f the valve-disk. In the bore of the valve-body, at the outer end thereof,

the same is provided on diametrically oppo H site sides with" two Y segmental coupling or lockingribs S S, which areseparated at their opposing ends by intervening gaps or spaces 8 s. In applyingthe couplingtothe valve body the same' is placedwith'its lockinglugs n in line with-the spaces 8 s and then moved into the outernend of the body until the lugs n are moved inwardly through the spaces between the locking-ribs S S and are arranged transverselyout of line therewith. As the coupling-stem is thus inserted in the body of the valve the sockets g at their front ends engage with. pinsq of the valvedisk, thereby connecting the valve-diskand' stem. Upon now turning the coupling, to-' gether with the valve disk and packing, the ports of the valvedisk and packing and the passage "through the valve are opened by bringing the ports'of the valve-disk and acking into register with those of the valveead.

While thus turning the coupling and opening the valve the locking-lugsn are moved behind theouter locking-ribs S S and. engage with the inclined rear sides tthereof, where by the coupling is drawn inwardly.

it represents a packing-ring, of rubber 'or I similar material, which is mounted, on the coupling-stem and adapted to be compressed between the annular flange 0 of the coupling and the outer end of the valv'ebody for producing a tight joint between these parts when the coupling is drawn inwardly by the wedge action of its lugs it against the inclined faces of the locking-ribs S.

For the purpose of detaching the coupling from the barrel the coupling,valvedisk, and

packing are first turned in the opposite direction for bringing the locking-lugs n opposite the spaces 8 between the locking-ribs S to permit of withdrawingathe stem fromthe valve-body. During this reverse or unlocking movement of the coupling the valve-disk coupled therewith movedinto its closed position,'whreby its'lugs H are engaged with the inner locking-ribs h for producing a tight joint. The rotation of the coupling is preferably effected by means=of adaterally-projecting handle 10, arranged on its nozzle. The spaces between the inner locking-ribs 71 are arranged in line with those between the outer locking-ribs S to facilitate the introduction of the valve-disk. The corresponding recesses on one side of the valve-body are preferably somewhat wider than those on the opposite side, and the lugs n and H of the couplingstem and the valve-disk are of corresponding shape, so as to compel assembling of these parts in a certain Way and insure coupling of the same in the proper manner.

It will be observed that the inner sides of the inner and outer locking-ribs incline in opposite directions, as shown in Fig. 5, so that upon turning the coupling and valvedisk for opening the valve leakage is prevented by the tightening action of the lock ing-lugs of the coupling against the outer locking-ribs, while uponturning the coupling and valve-disk in the opposite direction for closing the valve the valve-disk will be tightened by engagement of its locking-lugs with the inner locking-ribs.
